Justification:
The species has a relatively large distribution area and the habitat of the species is not affected significantly by human activity, therefore it is assessed as Least Concern (LC).

This species has also been assessed at the regional level as:EU27 regional assessment: Least Concern (LC) at the level of the 27 member states of the European Union.European regional assessment: Least Concern (LC).

According to AnimalBase, the species inhabits rocks and rock rubble in forests (not too dark), in trees, on calcareous substrate or on meadows with bare rocks showing through. It can be found above the timberline, up to 2,700 m asl. In France it is also found in dense populations in dry and sunny meadows devoid of rocks. In Britain it is usually in unshaded habitats.

It is a potential threat to this species if the rocks are destroyed by quarrying, by road construction or by other reasons. According to AnimalBase (2010) in central Europe it threatened by habitat destruction in forest management, and in Britain by changes of land use. However the total destruction of the whole habitat is not very likely, therefore this threat is mostly hypothetical.

Several sub-populations inhabit protected areas. The species is of Lower Concern in Austria, decreasing (4R) in Bavaria outside the Alps and Lower Concern in Germany (Reischütz 2007, Falkner et al. 2002). No conservation actions are currently required.
